以肿瘤直径作为追加因素重新评估冷冻切片在子宫内膜癌手术中的效用
Objective:
The purpose of this study was to improve the reliability of frozen section with the use of tumor diameter (TD) as an additional factor and intraoperatively to identify a subgroup of early endometrial cancers that would not require lymphadenectomy.
Study Design:
Data for 228 patients who underwent surgery with frozen section were analyzed retrospectively. Lymphadenectomy was performed in 86% of patients; the nodes were positive in 8%.
Results:
The accuracy of frozen section for myometrial invasion, grade, and low-risk prediction significantly increased with decreasing TD (P=.036) and was 98%, 95%, and 95%, respectively, when the TD was ≤3cm. Patients with a TD of ≤2cm and patients with a TD of 2-3cm who had low-risk predictors had no nodal metastasis; patients with a TD of 2-3cm who had intermediate-high risk predictors and a TD of >3cm with any level of risk predictors were at risk of nodal metastases.
Conclusion:
When the TD was ≤3cm, the low-risk group that is defined by frozen section can be predicted accurately and safely to remain lymph-node metastasis free
